Not a whinge, clearly lots of good work happening here, but any sign of access restrictions working again?

Is it me, or did this last update improve speed? My response time for everything from DNS queries to web page loading seems quicker. I checked my connection and my raw speed has not changed.

I don't have any proof, but yes, ping times from a wifi client to the access point, as well as through the wap/router out to the internet seem snappier. Also jitter is lower - multiple speedtests from multiple devices are handled smoothly with ping times out to the internet showing very little variance.

I was running 38570 for 33 days, then upgraded to 39101 for a couple days, then 39137 for a day, and now just upgraded and tested 39144. I'm not sure when these improvements happened, but 39144 looks fantastic at this early stage (4 hours uptime). Smooth upgrade - no issues.

did this upgrade at 14:30 so a little over 9 hours so far so good it is more responsive so i checked the svn, there was a downsize of code in there so maybe thats it i dunno but its for sure more responsive.

Appears the issue where it would only flash to one partition is solved. My guess is this is the reason for the shrink in code size. At around 37MB we've probably hit the max that these affected routers can handle. Id guess that the partitions are not actually equal sized. Maybe one is slightly smaller due the the boot loader. Really one of the few things that could explain the issue why the larger size of around 38MB firmware images would only successfully flash to one of the partitions.

Would make sense if it has some kind of banked flash memory. One memory bank contains the bootloader and one partition, the other memory bank contains the other partition. Router powers on, reads the bootloader off the 1st memory bank then reads the nvram variable to determine which memory bank to boot the firmware off of. Then the router continues to boot off the current memory bank or switches memory banks depending on the value

*EDIT*

Suspect my theory might be correct. Did some googling and found an image of the uboot bootloader used on these WRT routers. The uboot image clocks in just under 1MB

https://openwrt.org/toh/linksys/wrt_ac_series#corrupt_bootloader_recovery

Id suspect that one partition is smaller than the other with the difference being the size of the boot loader image, and some space for the uboot env variables and possibly the nvram that the firmware uses.

*EDIT AGAIN*

Some more digging, some more info. The actual layout of the flash memory space. Looks like the two partitions are equally sized, but we are now starting to bump up against the max size of 40MB per partition



Id guess the 38MiB syscfg partition is what ddwrt is using for /jffs seeing as the size just about matches the size of /jffs considering losses for formatting and the fact that the same /jffs is available no matter which partition you have booted.

*YET ANOTHER EDIT*

Appears the partitions are not equally sized, at least on my WRT1200AC

-rwxr-xr-x    1 root     root       37.0M Mar 12 02:24 mtd9


MTD4/Partition1 is 40MB
MTD6/Partition2 is 39MB

Looks like DDWRT also uses a slightly different flash partition layout than OpenWRT seeing as there are 10 MTD partitions instead of 9. The 256K MTD8 is the NVRAM space. If I cat out the dumped file it looks like the raw NVRAM values you would see if you did an nvram show at the command prompt. MTD9 is definitely the /jffs space. cating it out I can see ASCII contents of files that I have on my /jffs. So it looks like MTD7 and lower is the same as the OpenWRT layout, MTD8 is NVRAM, MTD9 is /jffs, MTD10 is that small bit of unused_area at the end.

MTD3 is interesting, looks like it has the "factory burned in" values used by the linksys firmware. Default wifi password, Default SSID, MAC, WPS Pin, Hardware revision, Date of manufacture, Serial number, Region (maybe for wifi?) Might be a way to override the region and set your AP to another region? I'm not going to try as I don't have a JTAG cable to unbrick if things go bad. I'll leave that to someone else. That is if DDWRT is even reading MTD3 for the region value? That could still be hard coded into the wifi radios.

WRT3200ACM 5GHz VHT160 still doesn't work and I need to choose my channel on HT80 now. 2.4GHz works fine, everything else appears to be ok.

VHT160 works fine on the 3200. You need to be careful of your channel selection and extensions. Availability depends on your region.

For my purposes I use channel 100 UUU(+14)
Take a look at https://en.wikipedia.org/wiki/List_of_WLAN_channels
to better understand availability.

WRT3200ACM V3 r39144 Firefox 65.0.2 (64-bit) webflash

OpenVPN CLIENT works fine (nordvpn server)
5GHz wpa2 CCMP-128 (AES)working fine 20MHz Mixed
2.4GHz wpa2 CCMP-128 (AES)working fine 20MHz Mixed
NAS via USB Samba also working fine


*** NOTE ***
Still unable to flash to my Buffalo WZR-HP-AG300H for those interested. Still on v3.0-r38581 std (02/06/19)

Should I assume that support for the wzr-hp-ag300h is over since its been quite some time since it would flash?

One thing that I've noticed in the latest builds is that link quality has dropped due to the inability to enable noise immunity if previously disabled. In fact, a good number of options disappeared in the latest releases including setting which compression method to use for wireless packets, radar detection, and antenna chains. These all exist on the near-useless Ath2, but Ath0 and Ath1 were Nerfed.

Router is WRT3200ACM

Looks like BrainSlayer worked on this recently after this release. See ticket https://svn.dd-wrt.com/ticket/6586

To help BS a bit (and the community), could you, please, indicate what the last build is, in which these options were still available?

It'll do some digging, but I can try.
I know it was in the "suggested" build when I first flashed it, but it's been a while and I'll have to narrow it down by flashing older versions.

I am definitely not the one who can help you further once you have found the build in question. I am too new to DD-WRT for that. But my hope is that there is someone else who can give you more helpful info at that stage.
